Patent CA-2161528-A1 (CA)
Title: Control of electric loads during generator failure in a multi-generator system
Inventor: VERNEY JAY FELTON
IPC: H02J3/14
Filed: 1994-04-21
Abstract: In response to the loss of a generator in an electrical power system, all operating electrical loads are automatically switched to a second generator, and the electric power system continues to provide power to all of the loads. The total power required to operate all operating loads is permitted to exceed the nominal rated capacity of the operating generator, and the winding temperature or other critical hotspot temperature of the operating generator is monitored to determine whether thermal stress limits will be exceeded. If the critical hotspot temperature the thermal stress limit, certain electrical loads are disconnected via a pre-programmed load shed priority schedule, and thereafter loads are re-connected as other loads are de-energized or if the critical hotspot temperature decreases.

Inventor: OHURA KOUJI
IPC: H04N9/093
Filed: 1996-03-18
Abstract: A three-dimensional resolution chart is used to adjust the position of a solid-state image detector 4 in a given image-forming optical system.  A plurality of blocks 10a are provided on an upper surface of a resolution chart 10. Each block 10a has an adjusting pattern A-D depicted on a slant surface thereof.  An image of each adjusting pattern A-D is formed on the solid-state image detector 4 through a master lens 2. The contrast integration value F is calculated based on the image of the adjusting pattern at each of a plurality of designated areas hj (j=1---n) on the slant surface of each block 10a provided on the resolution chart 10, to find out a specific position on each block where the contrast integration value F becomes maximum, thereby identifying the specific position as focus point of the master lens 2.  The back focus of the solid-state image detector 4 is calculated based on thus obtained focus point.   An optimum gradient  (.alpha., .beta.)  of  the  solid-state  image detector 4 is calculated based on three-dimensional relationship between plural focus points of the master lens 2 detected on the plural blocks 10a. Finally, each positioning mechanism 11 adjusts each  solid-state  image  detector  4  to  the  calculated  optimum position or at the optimum gradient.

Title: Stabilized, high solids, low viscosity smectite slurries, and method of preparation
Inventor: PAYTON JAMES
IPC: D21H17/68
Filed: 1994-09-23
Abstract: An aqueous slurry of smectite clay of elevated solids content, comprising an aqueous solution or emulsion of at least 0.2 % by weight of said slurry of a salt of a low molecular weight amine salt, in which is dispersed from about 10 to 47 % by weight of the slurry, of a smectite clay. The amine salt is effective to prevent the smectite from swelling appreciably, whereby the slurry can be shipped and stored without creating a gelling problem. The inhibiting or suppressing effect of the amine salt on the swelling of the clay and on gelling of the slurry is reversible upon subsequent dilution with water, thereby facilitating use of the smectite in typical applications, as a retention aid in paper making, or as a viscosifer.

Title: System and device for removing impurities from molten metal
Inventor: COOPER PAUL V
IPC: B22D41/58
Filed: 1996-05-13
Abstract: A system and device for removing impurities from molten metal comprising a pump within a chamber having an outlet port.      The pump creates a flow or stream of molten metal through the outlet port. One or more gas-release tubes are provided adjacent the outlet port, each gas-release tube having one or more gas-release openings adjacent the outlet port. Gas is introduced into the gas-release tube(s) whereby it escapes through the openings into the molten metal stream thereby removing impurities from the molten metal. The system may further comprise a gas-release block, having one or more openings, mounted adjacent the bottom of the outlet port, partially within the molten metal flow. Gas is introduced into the block through a gas-transfer device where the gas escapes through the openings and enters the lower portion of the molten metal stream. Finally, the system may further comprise a metal-transfer device for containing the molten metal stream. The gas-release device communicates with the channel and releases gas into the channel into the molten metal stream.

Abstract: To achieve this object, the winding machine of the invention includes two parallel wound web roll support rollers which are spaced apart and on which the roll being wound is supported. The gap between the support rollers and below the supported wound roll is to be pressurized. A pressure chamber is defined by the support rollers, the wound roll above, and from below by a cross member which bridges over the distance between the support rollers and closes the bottom of the gap. End walls close the ends of the chamber.      The cross member is movable between a sealing position where it is in contact with, or at least is sealed with, the two support rollers and bridges the gap between them to an open position where it opens the gap between the support rollers. The cross member is movable either down out of the gap, laterally out of the gap, or a combination of both, by reciprocating swinging, or oblique movement, and the like. The cross member has at least one passage which connects the pressure chamber with a source of compressed air through an intermediate conduit. An elongate transverse distributing pipe arranged at a distance from the cross member has a pressure connection through the conduit leading to the cross member.
